The Levine--Weinberger and Friedlander--Filonov inequalities for some classes of elliptic operators
T. Schmatzler
We consider the eigenvalue problem for certain classes of elliptic operators, namely inhomogeneous membrane operators and divergence form operator…

A second order approach to the Kato square root problem on open sets
Sebastian Bechtel, Cody Hutcheson, Tim Schmatzler +2
We obtain the Kato square root property for coupled second-order elliptic systems in divergence form subject to mixed boundary conditions on an open and possibly unbounded set in $…
